When I play table tennis with my Nitendo Wii console , on my TV, my gestures will look similarly awkward to anybody present in the room if they are not watching the game on the TV.

But controlling a display in a surgical operation with hand gestures may not yield the desired results as more precision is required especially if the doctor is performing and operation using Google glass as a display to assist the surgery.

@Susan: I agree with you that it would look awkward & funny initially till we are used to. I too feel that we are not there yet to use this in our day to day life. But first time I see somebody talking about a real good application about this technology:

Greenberg told EE Times. "This is especially important in a surgical setting where you can't touch things because your hands are sterile."

In Multnomah Village near where I live we have a guy who walks around and around the same circuit with music blasting in his earphones but all you can hear is him shouting out the lyrics. I can't wait for him to get a Myo to add hand gestures. He already does the air guitar thing :)

If you look at the video on page 2 you can see how awkward this looks. Imagine users with with a hands free phone and Google Glass...Not only will we now look like we're talking to ourselves but we can look like we're speaking in sign language to ourselves at the same time. I'm sure this will be very useful, but it will take getting used to.
